I am suddenly having listing errors when I try to list a pair of pants. In the description it has me select the size type. When I select regular or big and tall, it then locks the place where I select the actual size so I can’t put it in. Then when I finish the listing it gives me an error saying I didn’t put the size in the description. I can’t enter it if it is locked (it has an actual lock next to it.) can anyone tell me what I am doing wrong?
